SAD-IRON.

SPECIFICATION forming part of Letters Patent No. 787,816, dated April 11, 1905.

Application filed October 18,

Re it ltnown that l, OLEA 'lvinaoaun a citil zen ol the United States, residing at Canal I)over, county ot Yl`uscarawas, and State ot' Ohio. have invented new and useful Improvements in Sad-Irons, o'tl which the following is a specil'ication.

My invention relates to improvements in that elass ol sad-irons in which thc core or body proper olI the iron is surrounded by an iuelosing shell and an intervening dead-air space or non-heat cornluctorW-such as asbestos, mineral wool, &c., by which the radiation of heat t'rom the core is retarded,

rl`he object ot my improvement is to provide a sad-iron ot' the class described in which the lieatingwore and smoothing-plate are formed ot two separate parts, whereby the core may he separated Vtrom the smoothingplate, as well as the inclosing lshell, and placed in the lire-box or combustion-chamber of a stove or other heater in direct Contact with the coal, or it may, if desired, be heated over an oil or gas stove in direct contact with the i tlame, regardless ot the soot or dirt that might incidentally be brought in contact therewith, without iniuriously atleet-ing the smoothingplate ot' the iron: also whereby said veore may be heated to a red heat without liability olI burning clothes or unduly heating the hand ot the user.

lly invention pertains, further, to the device by which the locking-arms may be caused to simultaneously engage in the heating-core and smoothing-plato while the iron is being when removing the same trom the smoothingplate to the stove, whereby the necessity ot' employing a separate hoolt tor handling the core when the shell removed is avoided.

'l`he construction ot my invention is t'urther explained by ret'crence to the accompanying drawings, in which Figure l represents a side view. Fig. 2 is a transverse section drawn on line ,r ,rot Fig. l. and Fig. I), represents a top view o'tl the core and detachable smoothing-plate with the shell removed. l

1902. Serial No. 127,768.

Like parts are identilicd by the same ret'crence-letters throughout the several views.

A represents the core otI the sad-iron.

B is the inclosing shell.

C is the dt-tachable smoothing-plate.

The smoothing-plate C is provided around its marginal edg'e with a core-retaining flange l), which con toi-ms in shape lo the base otl the core and serves to retain the same in place, while the upper surt'aee ot' said flange serves as a base-bearing tor the lower edge ot the shell l, which is preferably made to closely tit against the same, so as to prevent the escape ot the heated air trom the space E between the shell and core..

The relative arrangement ol the heatingcore, the inclosing case, and the smoothingplate is illustrated in Fig. 2. The locking mechanism by which such parts are secured together consists otl a spring-clamp F, comprising two down wardly-extending arms G Gr and central portion H, formed integral.

l is an operating-handle.

The lower ends of the arms G are provided with inwardly-projecting trunnions` J .l and supportinghooks .V J. The trunnions .l have pivotal bearings in apertures l( K, formed in the sides ot' the case B, and their inner ends are adapted when locking said parts together to engage in thcaperturcs L L, lormed therefor in the vertical sides ot' the core A, while the hooks .Il engage the lugs IC, projecting outwardly from the sides ot the stainlards M, which standards M are formed integral with the smoothiiig-plate (l. lVhen the clamp F is in the vertical position shown in Fig. 2, the, trunnions l .l are held out ot' contact with the core A by the two side projections N N, formed on the sides ot' the case. '.lhe trunnions and supportinghooks are adapted to be thrown out ol engagement with the core and the lugs ot said standards when the elastic arms (i are brought into contact with said projections or contact-bearings N. ll'vhen, however, the clamp is inclined toward the right past the vertical, as shown in Fig. l, so that the side arms (i are brought out otl Contact with said projections N, said trunnions are thrown inwardly by the elasticity of said arms, when they engage in the apertures L L of said core, while the supportinghooks J' J engage beneath the lugs Kl K', whereby said shell, core, and smoothing-plate are all locked rigidly together, when they are ready for use.

When the core has become cool and it is desirous to exchange it for a hotter one, the clamp F is first thrown toward the left, as indicated in dotted lines in Fig'. l, whereby the hooks Jl are disengaged from the lugs K', while the trunnions J remain in engagement with the core, when the core may be removed with the shell from the smoothing-plate and placed upon the stove or other heater. This being done, the clamp F is again raised to the vertical, whereby the trunnions J are disengaged from the core, thus leaving the core upon the stove, whenthe shell is placed over another core and again thrown toward the left, whereby said trunnions engage in the recesses of the heated core, and the heated core is then removed from the heater and placed upon the smoothing-plate, when the handle is is again thrown to the right, as indicated in Fig. l, when all of said three parts are locked together as before.

A plurality of cores are preferably used with a single shell and smoothing-plate, so that one may be heated while the other is used. Each core is preferably provided with a lifting-bail O for the engagement of a lifting-hook, whereby the same is readily handled when placing it in or removing' it from the combustion-chamber of a heater. P is the handle of the said iron, which is of ordinary construction and is rigidly secured to the top of the shell by screws R.

It will of course be understood that by the construction shown I am not only enabled to heat the core to a much higher temperature than could be used in direct Contact with clothes, but I am thereby enabled to obtain such high temperature in a much shorter space of time by placing' the core in the {ireboX of a stove than it would be possible to heat the sad-iron upon the top of a stove, while owing to the fact that the core can be used much hotter than by other forms of construction in which thc cores are brought Ain direct contact with the cloth the necessity of changing the sad-iron as frequently as before is avoided, while owing to the further fact that the core itself is never brought in direct contact with the clothes lto be ironed the user is enabled to heat the same in direct Contact with the iame or coal regardless of the liability of its becoming soiled.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a sad-iron, the combination of a central heating core; a separable smoothingplate; a case inelosing the top and sides of the core, provided with a handle and adapted to rest upon the smoothing-plate at the base of the core; locking devices carried Aby the case for simultaneously engaging the smoothing plate and core; part of said devices being also adapted to engage and carry the core independently of the smoothing-plate.

2. In a sad-iron, the combination of a central heating core; a separable smoothingplate; a detachable core-inclosing case provided with a handle and adapted to bear against the smoothing-plate at the base of the core; means for locking the case to the smootl ing-plate and core, and for locking the case to the vertical sides of the core independently of the smoothing-plate.

3. In a sad-iron of the class described, the combination of a heating-core, provided in its sides, with opposing apertures for the reception of the trunnions of the locking mechanism; a detachable core-inclosing case; a separable smoothing-plate, provided with opposing standards or bearings for engagement with locking-hooks; a locking clamp, the lower ends of which are provided with opposing', inwardlyprojecting trunnions having pivotal bearings in apertures formed in the walls of said case, hooks adapted to engage with the retaining-bearings of said smoothing' plate; and means for simultaneously throwing' said trunnions and su pporting-hooks into and out of engagement with said core and the locking-bearings of said smoothingplate, substantially as set forth.

4. In a sad-iron of the class described, the combination of the heating-core A, provided with apertures L; a detachable core-inclosing case B, provided with outwardly-projecting contact-bearings N; a separable smoothingplate C, having opposing standards M, provided with lugs K for engagement with the locking-hooks J of the clamp; locking-clamp F, the lower arms of which are provided with inwardly-projecting trunnions J, and liftinghooks J, said trunnions J having pivotal bearings in the apertures K, formed in the walls of said case, and adapted to engage at their inner ends in the retaining-apertures L of said core, said trunnions and supportinghooks being adapted to be thrown out of engagement with said core and the lugs of said standards when the elastic arms G arein contact with said contact-bearings Y, and to be thrown into engagement with said core and lugs by their own elasticity when removed from contact with said bearings N, all substantially as and for the purpose specified.

In testimony whereof I afliX my signature in the presence of two witnesses.
